Affected: Ubuntu:16.04:LTS: golang-x-text, Ubuntu:18.04:LTS: golang-x-text, Ubuntu:20.04:LTS: golang-golang-x-text, Ubuntu:20.04:LTS: golang-x-text

The x/text package before 0.3.3 for Go has a vulnerability in encoding/unicode that could lead to the UTF-16 decoder entering an infinite loop, causing the program to crash or run out of memory. An attacker could provide a single byte to a UTF16 decoder instantiated with UseBOM or ExpectBOM to trigger an infinite loop if the String function on the Decoder is called, or the Decoder is passed to golang.org/x/text/transform.String.
